MPI debugging support in GDB?

Hi!

What is the current status for debugging MPI applications
with GDB? If
this is already possible/doable is there some documentation
available?
If this not possible are there any plans to implement this?

We use a small cluster to run MPI applications and otherwise
the system
consists only of free (beer/speech) software but to me it
seems that
proprietary and pricy debuggers are needed to debug MPI
application
(like TotalView or PGI CDK). There are several open software
MPI
libraries available (like OpenMPI and MVAPICH) but of course
a debugger
is needed every now and then.

Thanks!

Nothing special and no plans that I'm aware of.
